Oto-incompetentologist

A very long word used to describe an ear doctor that cannot/will not actually perform any mechanical intervention in a patients injured inner ear.

These doctors are often very well paid and drive luxurious sports cars, many moonlight in public hospitals one day a week to obtain state funded indemnity for their private practice with which they quickly return to afterwards (in their sports car) to continue their practice of oto-incompetentologist.

Word sources
otology o·tol·o·gy The branch of medicine that deals with the ear.
(stem of incompetēns) 1590-1600; Late Latin incompetent- unsuitable.

"I had a ringing in my ears and I felt dizzy so I went to the oto-incompetentologist, but he didn't do anything, in fact he did not have a clue what he was talking about and diddled me out of 200 bucks".
